Encoder only mode:
0 - Idle: No tuning or set-up
1 - Read information from the SLM EEPROM (CT Coder) and update the UniSP parameters
The parameter set to use is determined by the value of Parameters Transferred (Pr
x.28
).
2 - Idle - no tuning or set-up
3 - Idle - no tuning or set-up
4 - RESET the whole initialisation system
4 will hold the sequencer in reset.
Only read when Pr x.29
Action request is set high. Only effective in Encoder only mode.
0 - IDLE
1 - Parameters updated in the SLM EEPROM (CT Coder) for normal performance
2 - Parameters updated in the SLM EEPROM (CT Coder) for high performance
Servo motors:
Pr x.27 = 1:
• Rated motor current Pr 5.07 (in 10
th
Amp units)
• Rated motor base speed Pr 5.08 (in rpm)
• Number of poles Pr 5.11
• Flux angle Pr 3.25
Pr 3.25 is in electrical degrees. SLM EEPROM (CT Coder) data is in mechanical (65536 per rev) offset by +120°.
Pr x.27 = 2:
All for Pr x.27 = 1 and -
• Rated motor voltage Pr 5.09
• Stator resistance Pr 5.17 (per phase in 0.000) (delta (4/3 times per phase) in 0.00)
• Stator transient inductance Pr 5.24 (per phase in 0.000) (delta (4/3 times per phase) in 0.00)
• Current controller Kp gain Pr 4.13
• Current controller Ki gain Pr 4.14

• Stator resistance Pr 5.17 (per phase in 0.000) (delta (4/3 times per phase) in 0.00)
• Stator transient inductance Pr 5.24 (per phase in 0.000) (delta (4/3 times per phase) in 0.00)
• Current controller Kp gain Pr 4.13
• Current controller Ki gain Pr 4.14
• Power factor Pr 5.10
Pr x.27 = 2:
All for Pr x.27 = 1 (except Pr 5.10) and -
•L
s
value Pr 5.25 (per phase in 0.00) (limit 655.35mH) (per phase in 0.00)
• Motor saturation point 1 Pr 5.29
• Motor saturation point 2 Pr 5.30
In Encoder only mode, a parameter save cannot be performed with the drive in either RUN or STOP.
